[LLVMdev] [polly] scev codegen (first step to remove the dependence on ivcanon pass)

Maybe OpenMP / OpenCL codegen could separately handle the rewrite of in/out
variables for the outlined functions: the scalar and vector codegen don't need
to rewrite parameters.
What about moving a reduced version rewriteScevParams in the general
implementation of SCEV? That would make it available for other users.

It depends on how you implement it. You can do it in one swipe a...

Hi Tobi,
I would like to remove the SCEVRewriter code and replace it with a call to
SCEVAddRec::apply (see attached a patch that adds just this function). More
precisely I want to add another function called apply_map that applies a map
(loop -> expr) on a given scev. This is the apply function on a multi-variate
polynomial.
So here is an overview of how I would like the scev code generator
